I have a flowmast 40 series dumped under my truck. It sounds alright when I get on it, but is quiet most of the time. Unless you listened close, you could'nt tell I have aftermarket exhaust. The pipe after the muffler is very short and after reading the flowmaster book I noticed it did not meet the minimum length suggested. Would getting a longer turndown pipe help?
I was also wondering if I should get tips and run duals. It cost a great deal more and if I did that, I would want to be able to tell a pretty good difference. I have seen some people say they have URD Y pipes, but those seem kinda expensive. I was debating if I should try a magnaflow or a new muffler, but I just do not know. My previous trucks had V8s so all they needed was a simple flowmaster. I am just trying to find a way to make my truck have a better, deeper sound than it does now. Thanks for your help.
